Mexican Opal from Jalisco is prized for its transparency, fire and stability. I acquire this opal directly from the miners, who cut and polish the pieces by hand. The opal forms in a reddish matrix and when extremely good pieces are found, they carve away the matrix, and polish the remaining opal. The net result is a totally unique, highly lustrous free form. It can be set in jewelry or left in its own case to be displayed. This excellent example weighs 10.90 carats.
